Chantix binds to the same receptor in the brain that nicotine does. It activates the receptor, but not as strongly as nicotine. This has two effects:

  1. It decreases the cravings for nicotine because the receptor is being partially activated
  2. It decreases the pleasure of smoking since the nicotine is blocked from attaching to the receptor by the Chantix that is already there
